War is always cruel, and the cruel love war. While there are always the cruel at war, there are also always the just. It isn't just training and exposure that causes people, entire societies, to yearn for it. It is a matter of character. Them as are just cannot abide it, and they cannot understand how others do, either. People of sound character project their own understanding on others, just as do the weak, liars, and thieves. That is a ubiquitous human trait, unlike cruelty.

Thanks!
